Alcohol Dependency: Problem Drinking

Alcohol Dependency & Problem Drinking John Greenwald Edinboro University Introduction It is difficult to locate someone in the United States who feels that alcohol dependency and problem drinking is not a national problem. (Anton, R. 2010) Alcohol dependency and problem drinking has been at the forefront of policy debates at the micro, mezzo, and macro levels regarding healthcare expenses and outcomes, legal matters, and social implications for generations. Most times it is addressed in conjunction with drug abuse. (Anton, R. 010) A general population survey conducted earlier last decade estimated that the prevalence of problem drinking at 4. 65% and alcohol dependence at 3. 81% respectively in the United States. (Huebner & Wolfgang-Kantor, 2011) There are numerous ways to treat alcohol related disorders. Here are three of those interventions auricular acupuncture, 12 step based recovery programs, and moderation management program. Auricular Acupuncture Auricular acupuncture is a hol istic approach that originated in the United States during the 80’s.This form of acupuncture is widely used to treat alcohol dependency in the United States and United Kingdom as an alternative holistic approach. (Alster, M. 2010) The treatment uses five auricular acupuncture points referred to as NADA protocol, the acupuncture points are located in the ear. This intervention is rooted in traditional Chinese medicine. (Alster, M. 2010) The acupuncture points used during this treatment are similar from client to client. (Alster, M. 010) The treatment modality is used in conjunction with traditional alcohol detoxification protocols, as to protect the client from physiological harm from detoxing from alcohol. One study the reported short term benefits of this intervention included feelings of relaxation, contentment, and enjoyment mixed with more long term benefits like analgesia, increases in sleep quality, and a reduction in alcohol consumption, anxiety, and cravings. (Alster, M. 2010) In addition to the positive short term benefits there were some negative side effects that were reported such as feelings of light eadedness, burning sensations, and feelings of heat at needle sites. (Alster, M. 2010) Furthermore, there were some initial reports of anxiety even before treatment started which was found to be largely attributed to a client’s fear of needles, doubt of effectiveness, and fear of something foreign. (Alster, M. 2010) Many of these negative side effects dissipated as time passed. (Alster, M. 2010) The aforementioned study of this modality paints an overall positive view of this approach however another study drew correlations that were not as positive.The later study did find similar short term results which included a reduction in alcohol consumption and an improvement in overall psychological well-being. (Ashton, Nodiyal, Green, Moore, & Heather, 2009) However, the long term results failed to indicate significant indications of the overa ll effectiveness of auricular acupuncture in long term reduction in consumption, anxiety, and cravings. (Ashton et al. , 2009) 12-Step Based Recovery Programs Alcoholics Anonymous (AA) was founded in 1935, by Bill Wilson and Dr.Bob Smith, as self-help 12-step abstinence based approach to spiritual and character development. (Huebner & Wolfgang-Kantor, 2011) To this day, the AA fellowship is free to join for anyone who is alcoholic and wants to be a member which makes it an appealing option for many resource strapped clients and social workers. Later in the 1950’s the (AA) model was introduced into a professional setting by a non-profit organization called Hazelden Foundation, which is still used widely by many treatment facilities today. (Huebner & Wolfgang-Kantor, 2011)The Hazelden model calls for an individualized intervention plan, which includes family involvement, in the context of a 28 day inpatient setting combined with participation in AA while in treatment and post t reatment as a part of an aftercare plan. Typically in this model clients also undergo cognitive-behavioral therapy and/or motivational enhancement therapy which focuses on negative consequences resulting from alcohol use and identification of triggers which can be people, places, things, and events. (Huebner & Wolfgang-Kantor, 2011) In one study researchers found hat clients who suffered from alcoholism only, whom did not have a dual diagnosis or a co-occurring diagnosis, who utilized this intervention, had more abstinent days than those treated by other methods. These individuals showed significant positive outcomes which included a higher percentage of abstinent days and a decreased number of drinks consumed on drinking days. (Huebner & Wolfgang-Kantor, 2011) Additionally those who used medications to help manage side effects such as cravings and anxiety reported even better outcomes. (Huebner & Wolfgang-Kantor, 2011)Another study suggests that there is a lack of effectiveness and perhaps even harm inflicted by the 12 step model. (Miller, J. 2008) This study implies, â€Å"that despite decades of dominance of approaches based on 12 step principles, there have been no rigorously controlled research designs comparing 12 step treatment outcomes to no-treatment controls, and a recent review found no gains in outcome for 12 step interventions over alternative interventions. † (Miller, J. 2008) The counter research suggests that interventions which are based off of the Hazelden model â€Å"appear at best ineffective and perhaps even harmful. (Miller, J. 2008) Additionally it is noteworthy that there seems to be a lack of evidence based research that supports positive outcomes greater than negative outcomes. (Miller, J. 2008) The ethics and values of many helping professions are to empower clients to overcome their own issues and to achieve the right to self-determination. With that being said the 12 step model instills moral guilt, deviance, and labeling w hile infusing its members with feelings of powerlessness and dependence on the fellowship of AA thus using external rather than internal forces to effect change. Miller, J. 2008) The disease concept of alcoholism is a central tenant to the 12 step model; it â€Å"pathologizes† individual clients by removing focus from social and mental processes that may attributing to the alcoholic behaviors. (Miller, J. 2008) The intervention appears to â€Å"reinforce counter therapeutic cognitions and behaviors. † (Miller, J. 2008) Furthermore it has been noted that the 12 step culture itself can be hostile and scrutinizing towards non-adherents. (Miller, J. 2008) Moderation Management In the 1960’s professionals in the addiction field started to ask the uestion, can alcoholics learn to control their drinking or must they abstain completely from alcohol? Moderation Management (MM) is a mutual help fellowship designed for problem drinkers, not alcohol dependent people, who wi sh to pursue a goal of moderate drinking. (Lembke & Humphreys, 2012) MM’s is based on the problem drinkers individual ability to adhere to MM guidelines, which first includes a 30 day period of abstinence which is then followed by limits on daily alcohol intake. (Lembke & Humphreys, 2012) The primary goal being moderate drinking, not abstinence, which can be obtained by following a 9 step approach. Lembke & Humphreys, 2012) One study found that alcohol dependent clients found more positive outcomes with the 12-step recovery model. Data showed that people who reported to be only problem drinkers, without alcohol dependence, were able to recover from a diagnosed problem by a rate of 30-60% depending on whether they received treatment or just attended MM. (Lembke & Humphreys, 2012) There were reports of people who identified as problem drinkers, but were really alcohol dependent, who eventually left MM because they realized they could not drink in moderation and needed an abstin ence based intervention. Lembke & Humphreys, 2012) MM widens the range of attractive options available to people with alcohol disorders. Some clinicians feel that MM is a good place to start because it can be appealing to alcohol dependent people who are adamantly opposed to abstaining entirely. (Lembke & Humphreys, 2012) These same people eventually realize, because of MM’s 9 step program, that they are not able to drink in moderation and after defeat in this avenue may become more willing to try an abstinent only intervention such as AA thus serving as a starting point for anyone with an alcohol disorder. Lembke & Humphreys, 2012) Interventions such as MM reinforces many helping professions code of ethics in the sense that it puts the client in the control of finding what works best for them and aids them in achieving self-efficacy. (Miller, J. 2008) Conclusion To pick one intervention that I feel is the best pick for evidence based practice in Social Work would be difficul t. This is something that each clinician will have to decide on a client by client basis. Starting where the client is will help the Social Worker determine which intervention is best.I found that there is a lack of scientific research which gave any kind of correlations to any one of these interventions. Much of the research suggests that a combination of interventions along with starting where the client is what produces the best results and that no exact intervention was a smoking gun. If I had to pick one intervention that I feel is most useful in terms of helping a client who presented with alcohol dependency or who described themselves as problem drinkers, the intervention I would chose would be Moderation Management, if ethically appropriate.MM allows the client to choose his or her direction with where they are at in their alcohol dependency or problem drinking. Thus, allowing them to decide for themselves if they want to simply moderate their consumption or abstain entirely . References Zemore, S. , & Kaskutas, L.

Air Pollution Control in India

AIR POLLUTION CONTROL IN INDIA Air pollution  is the introduction of  chemicals,  particulate matter, or  biological materials  that cause harm or discomfort to humans or other living organisms, or cause damage to the  natural environment  or  built environment, into the  atmosphere. The first law against air pollution was passed in 1873. Air pollution can be classified broadly in two types: 1) Urban * Industrialization * Vehicles The increasing number of vehicles and industries constitute a major source for air pollution in urban areas. Heavy subsidy on Diesel also contributed to urban air pollution. 2) Rural * Indoor air pollution Indoor air pollution is caused due to poor availability of resources. It is directly and indirectly linked to lack of awareness and unaffordability which can be tackled by creating more employment opportunities for people. In India around 60% of the total population lives in rural areas and thus pollution caused due to indoor burning of solids is also very high. Case study: Bhopal Gas tragedy (1984) The Bhopal Gas Tragedy, involving a massive release of 40 tonnes heavier-than-air toxic methylisocyanate (MIC) gas, resulted in the death or injury of many thousands of people in the surrounding residential areas.It is attributed to the failure of safety systems, which allowed forty tones of the poisonous methyl isocyanate from the Union Carbide plant, to mix with water at a high temperature. Half a million people were exposed to the gas and 20,000 have died to date as a result of their exposure. More than 120,000 people still suffer from ailments caused by the accident and the subsequent pollution at the plant site. These ailments include blindness, extreme difficulty in breathing, and gynecological disorders. Controlling Air Pollution:National Air Quality Monitoring Program (NAMP)- The objectives of the N. A. M. P. are to determine status and trends of ambient air quality; to ascertain whether the prescribed ambient a ir quality standards are violated; to Identify Non-attainment Cities; to obtain the knowledge and understanding necessary for developing preventive and corrective measures and to understand the natural cleansing process undergoing in the environment through pollution dilution, dispersion, wind based movement, dry deposition, precipitation and chemical transformation of pollutants generated.UNEPs Indian Solar Loan Program- The aim of this effort is to help Canara bank and Syndicate bank develop lending portfolios specifically targeted at financing solar home systems (SHS). With the support of the UN Foundation and Shell Foundation, the project provides an interest rate subsidy to lower the cost to customers of SHS financing.

Statement of Purpose. The social work profession Personal

Of Purpose. The social work profession - Personal Statement Example The settings of social work practice may include hospitals, the homes of service users, schools, and other voluntary organizations (Horne, 1999). In my human service experiences and interactions with others, I have incorporated the values of social work in numerous ways. In the practice of my profession, I have paid significant attention to the social work values of service, dignity and worth of the person, social justice, integrity, importance of human relationships and competence (Sue, 2005). I have always held dear the social work value of service based on the reason that the primary goal of my profession is to help those in need to address the social problems, which they may be facing. As the social work value of service to clients purports, social workers should volunteer some of their professional skills with no expectation of financial return. I have successfully done this since I have assisted most of my clients without any expectation of getting returns from them. Another co re social work value includes social justice, which is based on the ethical principle that social workers should challenge social injustice (Vass, 1996). In my experience and interactions with others, I have pursued change on behalf of the oppressed and vulnerable persons in society. While working with diverse groups of persons, I have realized the need to acknowledge their ethnic, as well as cultural diversity. In the practice of social work profession, social workers should respect the dignity and worth of the person. As such, social workers should aim at treating clients and all persons in a respectful and caring manner (Turner, 2011). I have held this value to the latter; I have always promoted the self determination of clients in the decisions they make. In a socially responsible manner, I have sought to resolve the conflicts between client interests and interests of the broader society. Integrity can be regarded as one of the core values in the practice of social work; social workers have the obligation to behave in a manner that seems trustworthy (Shardlow, 2004). In my experiences with clients and interactions with people, I have always acted in line with the mission, ethical principles, values, and ethical standards of social work. I have acted responsibly and honestly; I have achieved this by promoting ethical principles and practices of the profession. In my human service experiences and interactions with people, I have recognized the significance of human relationships. I have assisted clients to understand that the relationships they have with people play an essential role in change. Moreover, I have strived to strengthen the relationships between people. This has allowed me to enhance, restore, and promote the wellbeing of families, individuals, and social groups. In my interactions with people and human service experience, I have successfully become competent in the field of social service. This has allowed me to enhance and develop the professi onal practice of my profession. Competence has increased my professional skills as well as knowledge; I plan to apply these in practice. I have had significant life experiences and relationships in giving help; these experiences motivated me to pursue social work. Social work entails working with clients at various levels, especially the needy, in order to improve their

Private Nursing Home Case Study Example | Topics and Well Written Essays - 1000 words

Private Nursing Home - Case Study Example The nursing home derives most of the financial resources necessary for steady functioning from the funds received from the local authorities' budget (constitute around 90% of the resources structure), the rest is financed through the residents' payments. For the analysis P.E.S.T.E.L. framework has been deployed. The factors of the external environment are grouped into political, economic, social, technological, environmental (ecological) and legal. The major factors for each group are listed and the degree of influence of each particular group of factors assessed. As the issue of post-retirement personal care and medical treatment of the elderly citizens is of high importance for the developed society, unsurprisingly the political environment has been influencing the state and perspectives of both private nursing and residential care homes through the history of their development. These two types for a long time has been treated and regulated separately until in 2001 they were legally addressed with the same types of requirements and legal provision. The most obvious and important trend is the significant increase of the number and share of the private sector nursing homes and decline in the share of these type of services provided by the public sector and administrated by the NHS. Privatisation of the earlier dominated by the public sector services had also affected provision of medical and care services for the elderly residents. For the particular nursing care home this trend's consequences are two-folds. First, it means shift in attention of the regulatory bodies towards the specific conditions of the privately owned homes and development of more specified requirements and constraints for the funding, facilities, care and medical treatment level, stuff competency etc. It may also result in increased funding opportunities for the privately owned nursing homes. Second, the increased competitive pressure caused by increased number of privately owned service-providers, both with regard to the residents' demand and funding provision, can become a market threat for the nursing home. Economic factors The general state of economy, income level and distribution and lifestyle of the population, determined by savings and spending preferences through the life are the important determinant of the nursing home's environment. General state of the economy of the country influences not only directly the economic and financial state particular business, but also the conditions of the customer base and local authorities, thus causing indirect influence on the nursing home. One of the factors to be considered is the growing income of the population and increased amount of funds available for spending in the late period of life. The improved financial position of many older people means that some are making a positive choice over long-term care; housing circumstances throughout life can affect decisions about housing and care later in life. (Peace, 2003, p.9) Another economic issue that is of great importance for the privately-owned nursing home, taking into account its size and limited resources, is the

I need to support these results by theoretical and empirical Thesis

I need to support these results by theoretical and empirical discussion from the previous study - Thesis Example In practice also, an empirical study by Professor Michael R. Powers and Martin Shubik seems to suggest that for any given nation or region such as the GCC, the positional market should be approximated to be equated to the square-root of the number of primary insurers in that given active market (Bennaceur and Goaied, 2001). What this also seem to suggest is that the number of primary insurers in an active market is always instrumental to the reinsurance dependence that will bring about total returns, which includes stock returns. Whiles this remains a valid argument, the correspondence between reinsurance dependence and stock returns in GCC insurance companies can easily be judged as either being positive or negative and whether the relationship is significant or insignificant. Looking critically at the GCC as a regional market, it can be realized that the major motive behind ceding companies in their reinsurance bids have had to do with a need to exchange insurance risk for credit risk. Because of this, there is always much care in ensuring that the reinsurer has an optimistic financial rating. Meanwhile, the chat below shows that as far as the total gross written premiums of insurance companies for the past 4 years are concerned, there have been significant rise across the entire GCC. What this means is that ceding companies always have enough grounds to bid into reinsurance, knowing that there are favorable financial rating. On the part of the reinsurers however, they would certainly benefit from as much increased stock returns as there are increases in the premiums. This positive relation is however described to be insignificant as this has not led to growth in primary business (Judge, et al, 2000) as the backbone of the reinsuring trade deals. A well articulated discussion on the relationship that presently exists between affiliated investment and stock returns in GCC insurance companies could best be outlined if the discussion is taken from the

Female Orgasm Essay Example | Topics and Well Written Essays - 2500 words

Female Orgasm - Essay Example Once at the point of a sexual high they are in a rhythmic stage which allows them to feel at the precept of having an orgasm. However, it can be factually said that many men have no idea of where to even begin in bringing a woman to this point, let alone to a climax because the woman's human anatomy is far more complex than the man's is. Therefore many women suffer from sexual frustration because they are not granted the same pleasure sexually that their male counterpart is. There are different forms of orgasms that are easier to obtain than from vaginal intercourse alone. These three different female orgasms are known as, clitoral, G-spot, and then of course the vaginal. Researchers who have studied the interactions of sex among human beings have found that many women have clitoral orgasms far easier than they do the G-spot or through vaginal intercourse. The reasoning in-behind this is the fact that women have to have clitoral stimulation while there is sexual penetration in order to gain a fulfilling orgasm, which many men fail to give to women. This is one of the reasons that it has been discovered many women fake their orgasms because their partners are not fulfilling their sexual needs. This can be validated and proven by showing that a study carried out by the American Medical Association defined the fact that 43 % of women are sexually dysfunctional and do not have regular orgasmic experiences during sexual interactions (Oumano 2000, p. 34). Als o, another 10 % to 15 % of women never even have an orgasm, not even through their own masturbation techniques. In cases such as these the male partner is not to blame but it is rather an anatomical dysfunction or it could perhaps be psychological as well. Also, viable evidence shows that many women, around 30 % to be exact never have an orgasm through vaginal penetration alone, which validates the fact that was stated, which emphasized that vaginal intercourse along with clitoral stimulation is the way to bring about a fulfilling orgasm for the woman.Because of this fact, and in order to demystify the vaginal and G-spot orgasmic experience, many researchers claim that the clitoral area is where all orgasms stem from (Oumano 2000, p. 35). However this can be refuted itself because many women claim that no two orgasms are ever the same and some are more intensely pleasing than others, especially those who are directly from clitoral stimulation and oral sex. Also, from a philosophical context, Fr eud stated that women who could experience an orgasm during sexual intercourse must be experiencing a vaginal orgasm as many philosophers, psychologists, researchers, and even doctors do not believe that the G-spot truly exists (Rudolf 1997, p. 63). This idea has led to many debates over orgasms among women as a woman knows her body far better than anyone else and she should know whether there is truth in the G-spots existence or not. Clearly women would not agree with Freud as they commonly know that there is a G-spot in their female anatomy. Also, of course if they have actually had the sensational experience of the penis making contact with this area then they assuredly know it exists. Therefore, the conflicting views leaves some puzzlement over why the

Ethical issues in Financier by Theodore Dreiser Essay

Ethical issues in Financier by Theodore Dreiser - Essay Example He went to friends of his at the Century Company and proposed they commission Dreiser to write for the Century Magazine three articles on Europe which might eventually be expanded into book length, and at the same time he directed Dreiser to ask Harper's for an advance on The Financier. The result was that on November 18 Century sent Dreiser a check for a thousand dollars for three articles and the option on any book he might write about his trip, and Harper's, upon his depositing with them the first part of his manuscript, agreed to advance him two thousand dollars on The Financier and five hundred dollars against the earnings of Jennie Gerhardt. In addition Harper's prepared to reissue Sister Carrie. When Richards suggested to Dreiser that even the Nobel Prize was now within his grasp, Dreiser re gained his confidence and on November 22 sailed with Richards on the Mauretania, explaining to an interviewer before embarking that in his new novel "I'm doing the man as I see him. . . . And when I get through with him he'll stand there, unidealized and uncursed, for you . . . to take and judge according to your own lights and blindnesses and attitudes toward life." In this spirit he was seeking to observe the "color of life." (Markle 10) Yet, baseless as Dreiser's worries mig... He remembered all the writing that he wished to do, wrote Mencken asking whether he would read the manuscript of The Financier, and although Richards tried to persuade him to visit the Hardy country, decided early in April that he must take the first available ship back to America. This ship happened to be the Titanic, but since it was on its maiden voyage, Richards thought it might be uncomfortable and preferred to secure Dreiser passage on the Kroonland, which arrived in New York at the end of the month, when Dreiser began at once completing The Financier. Dreiser wanted to call his whole trilogy The Financier, and the first volume simply "Volume One," but Harper's insisted that was commercially inadvisable. Dreiser wanted to shorten his novel so that it would not run to 800 pages, but Harper's was giving him no time to make adequate cuts. Mencken, however, was abroad when Dreiser returned from Europe, and it was not until May 7 that Dreiser could write to him from New York: "Lord[,] I'm glad to know you[']r[e] back. . . . I wish I could talk to you. I have a whole raft of things to discuss not the least of which is the present plan of publishing this book in 3 volumes -- 1 volume every 6 months. . . . For heaven sake keep in touch with me by mail for I'm rather lonely & I have to work like the devil." Mencken did keep in touch, and while during the summer Jug returned in what was the final attempt to solve the problem of loneliness, Mencken encouraged him in his work, read galleys, suggested the excision of irrelevant details and the expansion of certain incidents, and assured him: "You have described and accounted for and interpreted Cowperwood almost perfectly.

Final Exam - Essay Example To ensure that this become a success, FDR used radio as a mode of communication to convince American populace that the crisis had come to an end and that their deposits were safe following the introduction of the Federal Deposit Insurance Corporation (FDIC)1. The New Deal also created the Works Progress Administration (WPA), the Agricultural Adjustment Administration (AAA), and the Civilian Conservation Corps (CCC). The most eminent measure of the New Deal was the establishment of the 1935 Social Security Act, which resulted in the formation of Social Security Administration, employment compensation, as well as the national system of old-age pensions. According to a report, the Social Security provided federal financial assistance to the handicapped, orphans, and the blind. Additionally, the New Deal also gave way for the formation of a number of regulatory agencies, such as the Federal Housing Administration (FHA), which made homeownership affordable to millions of average Americans, the National Labor Relations Board, the Securities and Exchange Commission (SEC), as well as the Federal Communications Commission and the Civil Aeronautics Authority2. Despite the fact that the New Deal initiative lessened the impacts of the Great Depression, it did not end the depression. Report indicates that unemployment remained extremely high throughout the 1930s despite the New Deal being in place. At the same time, the economic growth remained slow. According to a report, America’s economy only recovered during the third term of Roosevelt’s reign when the increased demands of mobilization for World War II restored the country to full employment. In fact, report indicates that Adolf Hitler did more to end the Great Depression that Roosevelt did3. There are those who consider the New Deal as a good initiative for the U.S. government policy today. However, research indicates that the New Deal program negatively affected the poor

Marketing information system (MIS) Essay Example | Topics and Well Written Essays - 1000 words

Marketing information system (MIS) - Essay Example Putting into consideration factors such as market trends, changes and needs occurring in a market, and how the rival businesses conduct their activities is what a good marketer needs to do before venturing into a business (Michael, 2012 p. 67). The components of a Marketing Information System such as marketing research, internal records and marketing intelligence are most crucial when trying to obtain information on marketing (Esad, 2013 p. 35). However, to understand the role information systems play, what managers do must be examined as well as what kind of information they require to make decisions. How decisions are made as well as the decision problems that be solved by information systems must also be understood. This paper stands to examine the role Marketing Information Systems play in assisting managers with their marketing endeavors. Marketing managers have roles such as organizing, planning, deciding, controlling and coordinating. Any information has to be built with the role of a marketing manager in mind if it is to serve him/her well. Recently, there has been stressing on the aspects of behavior in management decision making (Jules, 2013 p. 35). On this, marketing managers are supposed to be highly voluminous in their jobs, work at high speeds, they should be diverse, or able to offer variety, they should also be specific, highly interactive and able to use verbal communication. Researchers suggest that a manager’s day has many tasks, but very little time assigned to each. Marketing managers prefer being speculative and gossiping in brief. This helps them keep up to date with up-to-date information. Routine and historical information, usually receives less attention. Even from researchers, marketing managers are found to prefer verbal communication in comparison to written information. Verbal communication has been found to offer more

A Unique Man Essay Example for Free

A Unique Man Essay The novel Into the Wild, written by author Jon Krakauer, takes place in the western portion of the United States during the late 1980s, early 1990s. Chris McCandless grew up in Washington D.C. and attended college at Emory University. He did not live an ordinary life by choice. He abandoned his opportunities after graduation and decided to travel out west for his own enjoyment and self-discovery. Chris McCandless is very different from an ordinary person because he explores life to the fullest and does not believe in society’s perception of what a person’s life should be. Chris McCandless did not need materialistic items to make his life more enjoyable; he only needed Mother Nature and his own motivation. For example, Chris does not want a new or better car because he is perfectly content with the Datsun, an old car passed down to him by his parents. His parents wanted to buy him a new car; however, he disagreed and became upset at the idea of having a new car in his possession. Chris’s perspective on the situation is that the Datsun is still in very good condition, therefore there is no reason to replace it with a more advanced car. Additionally, Chris donates over $24,000 to Oxfam International, a poverty eradication charity. The money that he donated to Oxfam International was originally given to him by his parents. However, Chris believed that this money was just a distraction and in order to make a point that he did not need the extra money and that he was satisfied with his life, he decided to donate it. Furthermore, before Chris began his adventurous journey for Alaska, he burned the rest of his money that he owned into ashes. He thought that money was just a distraction for what you could accomplish. One thing that Chris realized was that in life money is not everything, and happiness and tranquility cannot always be bought. The same thing goes for materialistic objects which are considered a distraction and unnecessary in the overall vision of the ideal life. In conclusion, Chris never needed materials or money to feel happy; he just needed motivation, nature, and the wild. Chris McCandless was always viewed differently by others since he lived an unordinary lifestyle. He would explain his theories and view of life to many others during his adventure to Alaska. For example, Wayne Westerberg, the first man to encounter McCandless on his vigorous adventure. Chris wasn’t prepared for the wild with the supplies he had, Westerberg helped him out with more advanced supplies. Chris shared his story with Wayne and they talked about their views on the lifestyle. Chris gave his input, but Wayne thought he was wild and out of his mind, but he liked Chris. Additionally, Chris encountered Jan Burres. Chris told Jan about his goals that he set for Alaska and the long adventure. At first Jan did not have must interest in of the matter. Then she gave her own insight on the hardships he would face and what he would need. Jan told Chris that he would have to acquire a job and shelter. Also, she said Chris would need plenty of food and water to prevent starvation during his traveling. Furthermore, Ron Franz was an old man Chris came across on his endeavor for Alaska. McCandless told his story towards his perspective on societies thoughts on what life should consist of. Franz thought he had interesting points and was a clever young man. Chris even convinced Franz to climb a mountain at one point to see a great view Chris had found. Chris encouraged Franz to take a risk and leave his everyday lifestyle and had him climb a steep mountain. In conclusion, Chris was an inspiration to many other people with his unordinary perspectives on the valuable things you occur in life. Chris McCandless would rather risk his life for his thrill of the adventure and nature than play it safe and be like everyone else. For example, McCandless has a main goal of traveling all the way to Alaska by foot. Chris did have a vehicle, the Datsun, but he abandoned the car and continued his quest for Alaska. On his way to Alaska he is offered help, such as food and shelter, and sometimes he would reject the help and continue on. He had the knowledge and skills to build his own shelter and obtain his own food. Also, he does not want or need valuables or materials to be satisfied. One example of this is the action of Chris donating over twenty thousand dollars to an organization. Another example is when Chris burns the remaining money he has left. Soon after he burns his money he abandons his longtime car, the Datsun. Furthermore, Chris prepares vigorously for hardships he could be unaware about of the wilderness. He would read multiple books as some preparation for the vigorous adventure from the United States to Alaska. He also gathered advice from multiple people he met during his traveling and took what people said into consideration. Chris possessed a guide that told him about different kinds of plants and if they were poisonous or not. In conclusion, Chris likes the idea of adventure, the challenges he will face, and the beauty of nature. Chris McCandless does what he believes life should consist of instead of accepting society’s view of what the normal life is. I think Chris succeeded in trying to live a transcendental lifestyle. He took on a grueling challenge that not many people would even consider. Even though he died on his adventure to Alaska, he was probably one of the bravest men to ever live. Also, Chris’ arrogance was not an obstacle to his success in achieving his goals, it was a confidence boost. His arrogance was a sign of confidence and knowledge, unfortunately he didn’t make it to Alaska. In conclusion, Chris succeeded in being what he viewed as a man and this brave man died trying to achieve a very unique thing.

The Importance Of A Sports Doctor

The Importance Of A Sports Doctor A sports doctor is a type of doctor who pursues in the prevention and treatment of injuries that affiliated with sports athletic activity. In professional sports, a sports medicine will be in group with a specific team and will be paid to care for the health for athletes. Sports doctors are most frequently associated with injuries to the joints, bones, and muscles. They focus primarily on injuries and conditions of the feet and legs are called orthopedic procedure. Sports doctors also work in athletic internal medicine, which concentrates on cardiac rehabilitation, lung performance, and circulatory issues combined with exertion. Sports Doctor Background A sports doctor studies health employing medical and scientific knowledge to prevent, observe, manage, and recover sports injuries. Exercise and sports science is the study of physiology and biomechanics that relates to the ability of the human body to adapt to movement and physical activity. When students graduated from studying exercise and sports science programs, they usually have big educational backgrounds because they can in both clinical and academic settings. Students who have a degree in sports science can also lead to career opportunities in fitness instruction, sports medical research, and nutrition. What Sports Doctor Focus On? A sports doctor focuses a lot on the medical phase of physical activity. Professionals of sports medicine, who work in the NFL, NBA, and other professional sports, train in the diagnosis and treatment of injuries that happen during sporting events, athletic training, and physical activities. It does not mean sports medicine degree can be involve the courses in injury prevention, analysis, therapy, and management, but it will involve understanding how illnesses and disease meets health and physical performance on injured athletes. If you earn a degree in sports medicine, it can lead a new career opportunities in athletic training, personal training, physical therapy, diet nutrition etc. You would work with some teams to help athletes and active people carry on the optimal health of becoming a sports medicine. Educational Requirements for Sports Doctors Sports doctors are fully trained medical doctor who would focus on sports medicine. In order to become a sports doctor, they have to do the same requirement of training before they can proceed. Sports doctor will need a Bachelors Degree to pursue in medical residency and school. In residency level, sports doctors are very determined but they can educate their focus on pre-med with great understanding of what elective courses will be best for their future career goals. Curriculum for sports medicine majors are: Physiology, Practicum in Athletic Training, Motor Development and Learning, Sports Psychology, Rehabilitation of Athletic Injuries, and Nutritional Science. Preparing for Sports Science and Sports Medicine School For becoming a sports medicine, you must require a college. Healthcare professionals, who concentrate in sport medical, draw seriously on scientific knowledge in a degree program. The class students will have a combination of math, medical, and science courses so that they can have all the training theyll need. Before making the decision on enrolling in sports medicine degree program, you should give some careful thoughts of personal interests and career goals. Students are often engage to the field of sports medicine because they have an enjoyment for sports. They should also have a serious interest in science and medicine and be willing to study hard in order to dedicate their studies to serve the needs of other athletes and active people. Successful sports healthcare professionals enjoy helping others, have an affinity for physiology and science, and possess a strong commitment to advancing and improving the health and physical capabilities of others. Successful sports healthcare professionals enjoy helping others and have a likeness for physiology and science, and acquire a strong commitment to advancing and improving the health and physical capabilities of others. A degree in sports medicine will require intensive and advanced studies of biology, biochemistry, physiology, anatomy, and other fields of science and math. With the strong fundamental skills in sciences and math, it will help them develop the skills they need in sports medicine college degree program. Job opportunities in the field are abundant and various for sports medicine. It can often be difficult to decide exactly on what kinds of sports science college students would like to study. If students are having trouble deciding exactly which path to take, they should try conducting sports healthcare professionals in the workplace. They can take an opportunity to ask acknowledged questions about the field to the professionals because they would like to give advice, guidance, and ideas about job o pportunities in the field. This can really help themselves focus on their own studies and choices of becoming a sports medicine. Once college students have made a decision to pursue a career in this field, they will make sure they know the differences between sports medicine degree programs to find an appropriate interest and goals. When they have gathered a lot of information about the options of becoming a sports medicine, the best information will be their best decision depending on their choice. Certificate Programs in Sports Fitness Sports and fitness certificate programs are options for new college students, current athletic trainers, nutritionists, and other professionals who want to develop a new set of skills. Certificate programs will teach students how to apply accepted physical and psychological theory for the world of sports to see most professional careers in this field are requires having college degree, but students can transfer their completed certificate credits to a Associate or Bachelors Degree program that will allow them to continue there studies on becoming a sports medicine. Associate Degrees in Sports Fitness In Associate Degrees, students must complete two years of class that will allow them an access to the fundamentals of sports science or they may train players in a specific part, like exercise science and fitness. If students want to study on advance careers in sport medicine, they must have a bachelors degree with the certificate programs. It can be possible to transfer the credits if they earned and minimize their time to a degree. Associate degrees are qualified to graduate for entry-level positions of sports and fitness. Many students choose to earn these degrees because they can move on directly into the workforce and then earn a bachelors degree when they get there. Bachelors Degrees in Sports Fitness After students earned the Associates Degree, they must earn a Bachelor of Science degree because it is the minimum requirement for employment of sports medicine professions. Mostly, earning a Bachelor of Science in sports science needs to have four years of academic study in college. These degree programs acknowledge the general concepts of physiology, medical science, nutrition, health, and related training. Many schools offer different occupations like physical therapy, athletic training, and nutrition. Masters Degrees in Sports Fitness After four years of study experience to earn a bachelors degree, students can work up to earn a Master of Science degree. The Masters Degree can let them do advanced training in achieve of progressing upper-level job opportunities. There are many healthcare professionals that pursue a Master of Science degree with a study in many different kinds of sports science, such as human movement, sports psychology, sports science, etc. Masters Degree, in sports and fitness, introduce students with advanced scientific concepts and procedures that will qualify them to better serve the needs of athletes and injured individuals. It also encourages them on focusing their knowledge, abilities and skills in a way that will make them grateful successors for advanced positions. It is their decision if students who want to pursue on earning a Masters Degree while to continue working full-time. They could earn more money than a Bachelors Degree. (World Wide Learn, Guide to College Majors in Sports Medic ine Science) Other Advanced Sports Medicine and Sports Science Degrees After students earn a certificate, Associates degree, Bachelors degree, and Masters Degree, they can choose to become a Medical Doctor degree and be into a sports medicine or surgical specialties. They can earn this degree to work in professional sports, like NFL, NBA, or etc. There are many students who are interested in helping, counseling, and monitoring the mental health of professional athletes and would likely to succeed in PhD program that focuses on sports psychology and psychiatry. Students can also choose to be Sports Doctor of Education, which would mainly be interested in teaching and advising sports science to new students who want to become a sport medicine. Trends for Sports Science and Sports Medicine Careers Professional athletes from colleges and high school can continue to push themselves to perform a better, faster, and stronger body.

Ofdm Techniques In Satellite Communications

Ofdm Techniques In Satellite Communications The concept of Orthogonal Frequency Division Multiplexing was first proposed in 1960 and developed in the 70s .All bandpass modulation schemes use single carrier by adjusting frequency, phase or amplitude .As Digital transmission uses high Bandwidth (data rates), the duration of bit information becomes smaller. The system becomes more vulnerable to loss of information from impulse noise,signal reflections and other impairments. As the bandwidth used by a single carrier system, the vulnerability to interference from other continuous signal sources become greater. ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING Modulation:-A mapping of the information on changes in the carrier phase, frequency or amplitude or combination. Multiplexing:-Method of sharing a bandwidth with other independent data channels. OFDM is a combination of both multiplexing and modulation. OFDM is a special case of FDM . In OFDM the signal is first split into independent carriers, modulated by data and then re-multiplexed to create a OFDM carrier. This can be done by using different modulation/demodulation techniques. The FDM systems requires a guard band between modulated subcarriers to prevent the spectrum of one subcarrier from interfering with another and not using bandwidth efficiently as in fig(i). If the FDM system uses a set of subcarriers that are orthogonal to each other. The use of orthogonal subcarriers would allow the subcarriers spectra to overlap,thus increasing spectral efficiency. As long as orthogonality is maintained, it is possible to recover the individual subcarriers signals despite their overlapping spectrums. . Fig(1): General representation of an FDM scheme with guard bands. Fig(2): Orthogonal FDM, eliminating the guard bands. OFDM can be implemented using the Discrete Fourier Transform (DFT). The sinusoids of the DFT form an orthogonal basis set, and a signal in the vector space of the DFT can be represented as a linear combination of the orthogonal sinusoids. One view of the DFT is that the transform essentially correlates its input signal with each of the sinusoidal basis functions. The OFDM signal can be a baseband signal or a band pass signal. For wired systems, due to the limited bandwidth of the wires, baseband OFDM signals are transmitted. For wireless communications, such as wireless local area network (WLAN) specified by IEEE 802.11a standard OFDM signal frequency bands are allocated in the RF frequency band. In this case, OFDM signals are generated in baseband first and up-converted to the RF band for transmission. Mathematically, the OFDM signal using the DFT/IDFT pair would be as shown [4]: DFT: X(k)=ÃŽ £n=0to(N-1) x(n) exp(-j2Ï€nk/N) IDFT: x(k)=(1/N) ÃŽ £n=0to(N-1) X(n) exp(j2Ï€nk/N) Figure (3): General block diagram of OFDM MULTIPATH CARRIERS As OFDM uses Multipath carriers they cause two problems Intersymbol Interference:-This occurs when the received OFDM is distorted by the previously transmitted OFDM symbol.Where as in single carrier the interfere is due to several other symbols instead of just the previous symbol. Intersymbol Interference can be removed by using guard interval. Intrasymbol Interference:-This occurs due to the interference amongst a given OFDM symbols own subcarriers. Fig(4): Performance evaluation of various modulation techniques with OFDM OFDM ADVANTAGES AND DISADVANTAGES OFDM offers many advantages over single-carrier modulations [1]: The maximum signaling rate (Nyquist rate) for a given channel can be approached without the use of sharp cutoff filters. It elongates the symbol period so that the signal is more robust against inter symbol interference caused by channel dispersions and multipath interference. It divides the entire frequency band into narrow bands so that it is less sensitive to wide-band impulse noise and fast channel fades. The effect of a slow frequency-selective fade is a separate complex gain on each sub-band signal and it can be removed by simply multiplying the signal by the conjugate of the complex gain-that is, equalization can be easily done by a one-tap equalizer. Different modulation formats and data rates can be used on different subcarriers depending on the noise level of individual sub-bands (the symbol periods are kept the same). In serial transmission, certain types of noise (such as time varying tone interference) may cause an entire system to fail; the parallel OFDM system can avoid this problem by adaptively reducing the data rate of the affected sub-bands or dropping them. OFDM can be implemented digitally using an inverse discrete Fourier transform and discrete Fourier transform (IDFT/DFT) pair (via the efficient fast algorithm IFFT/FFT pair), which greatly reduces the system complexity. OFDM is based on a parallel data transmission scheme that reduces the effect of multipath fading and makes the use of complex equalizers unnecessary. OFDM achieves high spectral efficiency by allowing the sub-carriers to overlap in the frequency domain. The sub-carriers are made orthogonal to each other therefore there is no Inter-Carrier Interference. If the number of sub-carriers in N, the total bandwidth required is BWtotal=(N+1)/Ts. For large values of N, the total bandwidth required can be approximated as BWtotal=(N)/Ts. On the other hand, the bandwidth required for single carrier transmission of the same data is BWtotal=(2N)/Ts. Thus we achieve a spectral gain of nearly 100% in OFDM compared to the single carrier transmission case. OFDM also have DISADVANTAGES over single carrier modulation systems The OFDM signal has a noise like amplitude with a very large dynamic range, therefore it requires RF power amplifiers with a high peak to average power ratio. It is more sensitive to carrier frequency offset and drift than single carrier systems are due to leakage of the DFT. High sensitivity to synchronization errors. Nonlinear effects generated by the power amplifier may introduce inter carrier interference and thus destroy the orthogonality. Larger sidelobes may result in sensitivity to frequency. APPLICATIONS OF OFDM Wireless LAN Applications HIPERLAN/2 HIPERLAN/2 is a Wireless LAN application defined by the ETSI. HIPERLAN/2 handles data rates between 6-54 Mbit/s. HIPERLAN/2 provides a DLC layer on top of which an IP based broadband network can be implemented. The Physical layer of HIPERLAN/2 is based on the Orthogonal Frequency Division Multiplexing (OFDM) modulation scheme. The Numerical Values of OFDM parameters in HIPERLAN are given below: Parameter Value Sampling rate fs=1/T 20 MHz Symbol part duration TU 64*T 3,2  µs Cyclic prefix duration TCP 16*T, 0,8  µs (mandatory); 8*T, 0,4  µs (optional) Symbol interval TS 80*T, 4,0  µs (TU+TCP) ; 72*T, 3,6  µs (TU+TCP) Number of data sub-carriers NSD 48 Number of pilot sub-carriers NSP 4 Sub-carrier spacing à ¯Ã‚ Ã¢â‚¬Å¾f 0.3125 MHz (1/TU) Spacing between the two outmost sub-carriers 16.25 MHz (NST*à ¯Ã‚ Ã¢â‚¬Å¾f) IEEE 802.11 The IEEE 802.11 committee has a standard similar to the HIPERLAN. Its OFDM parameters are as shown below: Data Rate 6,9,12,18,24,36,48,54 Mbps Modulation BPSK, QPSK, 16-QAM, 64 QAM Coding Rate 1/2, 2/3,3/4 No of Sub-Carriers 52 No of pilots 4 OFDM Symbol Duration 4 us Guard Interval 800 ns Sub-Carrier Spacing 312.5 kHz 3 dB bandwidth 16.56 MHz Channel Spacing 20 MHz Satellite Communication applications Digital Audio Broadcasting (DAB) Digital Audio Broadcasting is a new multimedia technology, with a good sound quality and better spectrum efficiency. The DAB system samples audio at a sample rate of 48 kHz and a resolution of 22 bits. Then the data is compressed to between 32 and 384 kbps. A rate  ¼ convolution code is used with constraint length 7. The total data rate is about 2.2 Mbps. The frame time is 24ms. QPSK modulation is performed at the transmitter. The advantage of using OFDM for DAB is that the OFDM suffers very little delay spread and has high spectral efficiency. Digital Video Broadcasting (DVB-T) Digital Video Broadcasting is an ETSI standard for broadcasting Digital Television over satellites, cables and through terrestrial (wireless) transmission. Terrestrial DVB operates in either of 2 modes called 2k and 8k modes with 1705 carriers and 6817 carriers respectively. It uses QPSK, 16-QAM or 64-QAM subcarrier modulations. It also uses pilot subcarrier for recovering amplitude and phase for coherent demodulation The major use of OFDM can be observed when multiple techniques can be transmitted and received at the same time. This can be done with the help of MIMO OFDM. The transmitted signal will be received by various VSAT networks based on the corresponding frequencies. Further, processing of this signal and error corrections, the original signal is retrieved. For example, consider that a DAB, DVB and other geological information is received by various antennas as shown in the figure. NEWEST RESEARCH AND FUTURE TRENDS OF OFDM One of the methods developed in the recent years is that the convolutional coding (CC) and trellis coded modulation (TCM) are combined with OFDM for a Rician fading channel according to the specifications given by the Iridium system. Here, the bit error rate (BER) performance of OFDM with 8-PSK and 16-QAM modulation techniques along with two different coding schemes are considered for a LEO satellite channel. Trellis coded OFDM gives the best performance compared to convolutional coded OFDM. The peak to average power ratio (PAPR) can be reduced approximately by 1.5 dB with the help of the partial transmit sequence technique (PTS). Later, some more research and simulation results proved that the Turbo Coded (TC) OFDM performed better than CC or TCM with OFDM [6]. Satellite mobile systems are developed to provide connectivity between remote terrestrial networks, direct network access, Internet services using fixed or mobile terminals, interactive multimedia applications, and high data-rate transmissions. Most of these research and development scenarios have considered the Non-Geo Stationary Satellite (NGSO) network for providing satellite-based mobile multimedia services because of its low propagation delay and low path loss. As a result, new generations of broadband satellite communication systems are currently being developed to support multimedia and Internet-based applications. For example, the Spaceway system provides downlink transmission rates of up to 100 Mbps, and a total capacity of up to 4.4 Gbps. In order to significantly increase the capacity of 4G broadband satellite systems, current research aims at developing new advanced technologies [5]. In the wireless system, OFDM is the main basis for several television and radio broadcast applications, including the European digital audio broadcasting (DAB) and high-definition TV (HDTV) terrestrial broadcasting as well as North American digital radio broadcasting. By the beginning of the 21st century, OFDM has been adopted as standard for new high-rate wireless local area network (WLAN), such as IEEE 802.11, HIPERLAN II, as well as the Japanese Multimedia Mobile Access Communications (MMAC). Currently, many researches are underway to devolve an OFDM-based system to deliver mobile broadband data service at data rates comparable to those of wired services, such as DSL and cable modems. Moreover, OFDM technology is a very attractive candidate when targeting high quality and high flexibility in mobile multimedia communications over satellite systems [6]. When the research interest is in the integration process of 3G terrestrial systems with the satellite domain, the conventional frequency division MAS (FDMA) system looses its flavor in competing with the code division MAS (CDMA) and time division MAS (TDMA)-based systems for its very high bandwidth (BW) requirement. Moreover, in satellite systems, it is shown that CDMA system outperforms the FDMA system when diversity is taken in to account. In this case, OFDM replaces FDMA with manifold advantages. Currently wideband CDMA (W-CDMA) and OFDM/TDMA techniques are successfully in use in terrestrial mobile multimedia systems. Therefore, these two Multiple Access schemes (MASs) are getting considerable attention [7] in mobile multimedia communications for Non-Geo Stationary Satellite interface.

Rodrigo’s Reconcile Essay -- essays research papers

Rodrigo’s Reconcile   Ã‚  Ã‚  Ã‚  Ã‚  Reconciliation means to bring back together. In Reconciliation the way we are brought back together with the community is by asking forgiveness. Forgiveness means to pardon or spare. In Greek it means to send forth, put away, and yield up. The other meaning is to give up the desire to punish or to cancel a debt. Jesus gave us the sacrament of Reconciliation. We were granted this sacrament so whenever we turn away from God we have the choice of asking forgiveness so we can be reunited with Him.   Ã‚  Ã‚  Ã‚  Ã‚  The four steps in the sacrament of Reconciliation are confession, contrition, penance, and absolution. The first step is confession which allows people to reunite with God by admitting their sins. Before you can heal mentally and spiritually you have to admit your sins. Rodrigo, who was a former slave trader and mercenary, committed a grave sin. He killed his younger brother who he raised as a kid when his parents died. Rodrigo didn’t mean to kill his brother, but it happened during a time of rage against his brother for stealing his girlfriend. Rodrigo knew and accepted the fact that he killed his brother, but he couldn’t let it go. He was really hard on himself.   Ã‚  Ã‚  Ã‚  Ã‚  After realizing you have sinned against someone, the next step is asking forgiveness from God. Rodrigo Mendosa after killing his brother could not ask forgiveness from God. It was because he couldn’t forgive himself. He needed someone to help him and be with him. At this time along cam...

Enhanced British Parliamentary Papers on Ireland, 1801-1922 :: Government Politics Political Essays

Enhanced British Parliamentary Papers on Ireland, 1801-1922 The British Parliamentary Papers on Ireland (BPPI) are an indispensable primary source for virtually every historian (and many non-historians) working in most fields of Irish history, and the history of Anglo-Irish relations, during the period of the Union (1801-1922). We have identified some 13,700 official publications relating to Ireland from the House of Commons[1] Sessional Indexes for this period, ranging in scale from short bills of a few pages and reports, to the massive social inquiries with volumes of minutes of evidence exemplified by the decennial censuses, the Poor Inquiry Commission (1836) and Devon Commission (1845) reports, each of which were multi-volume documents covering thousands of pages. Subjects covered by BPPI range from government, politics and administration, to finance, agriculture and industry, communications, emigration, social conditions, poor relief and health, population, law and order, education, cultural institutions, religion and language. The types of evidence contained are extremely varied, from statistical series and accounts to lightly- or unedited transcripts of emigrants’ letters and witness interviews from across the social spectrum. Obviously the BPPI are elite documents, created by the Government, Parliament and state agencies for the purposes of governance, administration, and the creation of official knowledge. This naturally implies an official bias in what was thought relevant of observation, what data was collected, and what was selected for publication. The principal value of the BPPI might thus be taken to lie in what they tell us about governing knowledge, preoccupations, strategies and ideologies – all crucial in themselves for an understanding of the British-Irish relationship in the period between the Act of Union and the Irish Revolution and the partition of the island in 1919-22. But the BPPI can also provide us with much more than the ‘official view’. British governance of Ireland took place in the context of executive responsibility to Parliament, a body which contained growing numbers of oppositional and nationalist Irish members who could demand returns of official data and serve on committees and commissions of inquiry, and beyond Parliament (however imperfectly) to an Irish as well as a British public opinion, increasingly conscious through the burgeoning popular press of the proceedings of Parliament. Irish newspapers, for example, carried not only verbatim accounts of parliamentary debates, but long extracts from the BPPI, and debated their findings and implications in editorials. The BPPI were very much part of the public life of 19th and early 20th-century Ireland.

John Gibbons Truth in Action :: John Gibbons Truth Action Essays

John Gibbons' "Truth in Action" ABSTRACT: John Gibbons tries to show that the notion of similarities and differences between different cases of events reveals the relevance of relational properties, which are of causal relevance. Based on such considerations, Gibbons' main claim is that the truth value somebody assigns to his or her beliefs has causal power. This means that the deflationary theory of truth becomes false. The questions therefore are: (1) What are the similarities and differences between different cases? (2) What kind of properties are relational properties? (3) What is the causal relevance of such relational properties, and why should the truth value be of causal relevance? (4) Why can Gibbons not show that the truth value has the relevant causal power? On the basis of some examples John Gibbons tries to show that the notion of similarities and differences between different cases of events reveals the relevance of relational properties, which are of causal relevance. Based on such considerations Gibbons' main claim is that the truth value somebody assigns to his beliefs has causal power. And so the deflationary theory of truth becomes false. So, the questions are: what are (i) similarities and differences between different cases, (ii) what kind of properties are relational properties, and (iii) what is the causal relevance of such relational properties, and why should the truth value be of causal relevance? (iv) Why Gibbons cannot show that the truth value has the relevant causal power? (i) What are similarities and differences between different cases? Gibbons assumes events (1) to speak about cases of particular actions and of particular physical states of affairs, however, he does not distinguish them, he simply speaks in both cases about behavior and their causes or about behavioral events. The example of behavioral events E1 and E2 Gibbons uses is the following: The pure actions A are: A1 Marcia stopped at the red light. A2 Greg stopped at the red light. The action for achieving A: (2) AA1 squeezing a lever with the right hand AA2 pressing a pedal with the foot Additional features of A: af1 cast a shadow in my direction ??? af2 ??? (3) The aim of action A is: aiml wanted to avoid getting a ticket. aim2 wanted to avoid getting a ticket.

Simulation Reflective Journal

Simulation Reflective Journal Look back We were four in our group and we were given a scenario of a patient who was having an anaphylactic reaction from bee sting venom. The group agreed that I will be the primary nurse. As the primary nurse, I knew that I had to lead and supervised our group in responding to the emergency situation at hand. Having played the role of a primary nurse in this simulation, I have gained meaningful experience, which I can use in my future nursing practice. Elaborate Being the primary nurse, I assigned each of my group members to a specific task. I assigned one colleague to assess the vital signs of the patient. In the scenario there were two medications that should be administered to the patient, the epinephrine and another anti-histamine drug, so I assigned two persons to prepare it. There was a delay in the administration of epinephrine since there were two epinephrine pre-filled automatic injections in the medication box. The person I assigned to it was confused which of the two will be used, so she asked me which one will be used. I’m not really sure what to answer, so I just told her to select the latest one and inject it immediately. Unfortunately the person who will administer the epinephrine did not know how to use the pre-filled automatic injection and neither did I. It took us sometimes to figure out how to inject it. As for the other medication, it was not stated in the scenario when to inject it. The person in-charge of preparing the medication also asked me when to inject it and again I’m not sure what to answer. I told her to wait for a few minutes before injecting it. I belatedly remember that in case of doubts, this matter should be referred to the doctor. Analyze The simulation has made me realized how crucial the role of the primary nurse during emergency situation. One must be thoroughly trained and must possess critical thinking skill before becoming a primary nurse since being the leader, members of the team tend to seek guidance to promote efficient nursing care. As a primary nurse in this simulation my colleagues addressed questions to me about the medications that are critical to the patient’s survival. My answers were not decisive which reflect my weak critical thinking skill. For example, when it comes to medication administration, in instances where things are not clear, it should always be referred to the doctor which in this case I belatedly remembered. Nurses should also make sure that they knew how to use all the equipment that is used in the nursing care. In a medical emergency situation, every second counts. In the simulation, epinephrine administration was delayed since the nurse did not know how to use the automatic injection. Over-all the simulation had a significant impact to my learning process. Revise For the next simulation, I am hoping that I have improved my critical thinking skills in nursing to effectively perform whatever role I will have. Moreover, since simulations are actual situations in real life clinical settings that are being played out by the students, I will research on applicable evidenced based nursing intervention and applied it during the simulation. Applying this type of intervention during the simulation will reinforce my knowledge of effective nursing intervention and will enable me to acquire a more meaningful experience that could be applied in actual clinical setting. I will also try my very best to find out what possible equipment will be used in carrying out nursing care for a given clinical setting that will be simulated aside from the equipment being used in assessing routine vital signs so that I could learn in advance how to use it. New Trial Experience gained from this simulation is very useful in my clinical practice and future nursing practice. It was instilled in my mind that appropriate nursing training and critical thinking skill is a must in any clinical setting in order to deliver efficient nursing care. In this regard I will honed my nursing skills through readings and diligent practice and apply it in actual clinical setting, I will discuss with the instructor, relevant observations in clinical practice to acquire thorough understanding of the patient’s situation in order to identify and apply evidenced based nursing intervention.

Examining Government Regulations

The current government regulations I researched pertain to the clinical guidelines and the civil rights of persons living with HIV/AIDS in Portland, Oregon. Many people living with HIV/AIDS, at some point during their illness, find themselves in need of housing assistance and support services. Stable housing promotes improved health, sobriety or decreased use of alcohol and illegal drugs, and, for some, a return to paid employment and productive social activities. As the number of people living with HIV/AIDS continues to grow in both urban and rural areas throughout the United States, stakeholders must find new ways to address their needs to promote the health and well-being of these individuals and their families. Increasingly, maximizing the resources available to people who need them requires partnering across mainstream housing and human services systems to ensure continuity of care, program efficiency, and that there is â€Å"no wrong door† to assistance for clients at risk. The United States Department of Health and Human Services recommended public health law reform as part of its Healthy People 2010 initiative. Public health law in many states is ripe for reform. Oregon state legislature has suggested that existing state statutes are ineffective in responding to contemporary health threats for many reasons. These statutes pre-date modern scientific and constitutional developments and lack adequate standards of privacy, due process, and risk assessment. Forty percent of Oregonians with HIV need housing assistance, and a survey of Oregon service agency representatives cited the lack of affordable housing as the number-one barrier to stability for Oregonians living with HIV/AIDS. Critical issues were identified and recommendations developed to improve the ability of these systems to cooperatively meet the housing and services needs of people living with HIV/AIDS in Oregon. The obstacles that would prevent me from meeting the needs of people living with HIV/AIDS are 1. Limited Awareness of Resources Dedicated to People Living with HIV/AIDS Many potential housing and services partners lack awareness or accurate knowledge of existing resources dedicated to, or which can be used to serve, people living with HIV/AIDS, and that lack of awareness may limit partnerships. 2. Confidentiality Concerns The need to maintain client confidentiality restricts the ways that OHOP housing coordinators and other organizations and individuals can publicize their activities and resources. . Limited Staff Capacity and Knowledge HIV Care and Treatment staff may lack familiarity with aspects of partner systems, including affordable housing, and have limited resources and time to conduct marketing and outreach to potential partners and planning bodies. Discrimination adds to the daily struggles faced by the growing number of people living with HIV/AIDS in the United States – people who are predominantly poor and disproportionately African American or Latino. Every agency’s biggest problems facing their clients involve meeting basic needs – coping with poverty, hunger, illiteracy, inadequate medical care, lack of transportation, and homelessness. In addition to those basic needs issues, people with HIV face a series of critical civil rights problems. Individuals living with HIV/AIDS need to know their rights and need the resources to advocate for themselves when their rights are threatened. They also need national legal organizations like the ACLU AIDS Project to enforce their civil rights and civil liberties through litigation, public education and legislative advocacy. Recommendations: †¢ Develop simple, discreet material to publicize OHOP and related services and opportunities, and distribute it widely. †¢ Present to current and potential partners, including faith-based and community-based grass roots organizations with information tailored to their interests. †¢ Engage provider agency staff, clients, and other regional participants in publicizing the need, opportunity, and benefits of investing in housing and services for people living with HIV/AIDS. †¢ Focus attention on improving coordination with planning, data, and other elements of homeless systems. †¢ Promote Shelter Care and other bonus projects through agreements to streamline or share sponsor administrative costs. †¢ Conduct outreach and seek partnerships with landlords and property managers. Oregon Housing and Opportunities in Partnership (OHOP) Program Many people living with HIV/AIDS find themselves in need of housing assistance and support services at so me point during their illness. As many as 60 percent of all persons living with HIV/AIDS report a lifetime experience of homelessness or housing instability. Stable housing promotes improved health, sobriety or decreased use of alcohol and illegal drugs, and, for some people living with HIV/AIDS, a return to paid employment and productive social activities. The federal Housing Opportunities for Persons with AIDS (HOPWA) program provides funding, distributed by both formula and competition, dedicated to the housing needs of people living with HIV/AIDS and their families. This funding is not only necessary but critical to have the needs of people living with HIV/AIDS met adequately. Examining Government Regulations The current government regulations I researched pertain to the clinical guidelines and the civil rights of persons living with HIV/AIDS in Portland, Oregon. Many people living with HIV/AIDS, at some point during their illness, find themselves in need of housing assistance and support services. Stable housing promotes improved health, sobriety or decreased use of alcohol and illegal drugs, and, for some, a return to paid employment and productive social activities.

English As A Second Language Program Essay

An ESL or English as a second Language program, as the name suggests is for students or people in general who do not speak English as their first language and have an interest in learning this language for certain reasons which may range from applying to a college or university in United states or elsewhere or they would want to get accustomed to this language for the purpose of conducting business overseas, for communication with peers at work or it can be for the simple reason of communicating with people at different situations. In this article we are going to focus on ESL programs for students at a school district, comparing and contrasting on the ways they are executed and the ways they should be executed. English as a Second Language programs for students are offered to students by either scheduling classes in between their regular course classes or they can be undertaken as a separate programs by certain individuals who are accommodated in the vicinity of the university. Today, since the ratio of international students is increasing at an alarming rate in United States or Canada, offering an ESL program is more of a legal requirement for most districts so that all students are taken forward together at university or when they enroll into one in future. It is also due to this very fact that a lot of emphasis is given to ESL programs at elementary and middle school levels to prepare students to use English as a channel of communication in future. The execution and the effectiveness of these programs however, vary with different school districts depending upon trained teacher, the program and the dedication of the students themselves. The duration and intensity of an ESL program varies with the individual or university requirement and can be full time or part time, ranging from a couple of weeks to even a year. These details as mentioned do differ, so for example the ESL program offered at the Greenwich public school which aims at providing students academic and communication skills In order for them to succeed in U.S universities as effectively as possible. The elementary school offers this program for an average 2- 4 years with one to eight hours of instruction every week depending upon the grade and language individual needs of students. The school also focuses on very small groups and emphasizes individual attention to students to better understand their weaknesses and fill I the gaps. The Greenwich Public School district has been offering ESL programs for the past 28 years and has seen an influx in the number of ESL students over the years. In the year 2004-05 approximately 731 students enrolled in the program altogether from 54 countries. The elementary school curriculum includes a variety of materials according to student needs such as work books, songs, CD’s, learning of poems, class presentations etc. this program is more content based   and strong emphasis is give on the reading aspect in this program.   The program is organized around themes and aims at teaching critical thinking along with language skills to enable success in mainstream class rooms. In more specific terms this ESL program for elementary students includes Theme based English series which includes work books, posters etc. Group activities (theme based) which tend to explore literature along with songs, activities, TPR games etc. Miami Linguistics, which are designed for ESL beginners in a sequential reading manner. In Greenwich Public School, after completing the elementary school program after reaching grade 2 or grade 3, ESL students are expected to formulate questions, read outside of class, compare materials in a text and also contrast them. They are also able to express a story in their own words with proper understanding and expressions, write small paragraphs and initiate conversations. After completing the basic ESL program for elementary school, students can decide to move out of the program or advance to higher level middle school ESL program, which has its own curriculum and particular hours to be covered aimed at developing proficiency in English language. Placement in this program is based on entry tests and educational history. After looking at the details of different ESL programs offered by various institutes, if one actually compares them with reality, one can say that ESL programs put students under a lot of stress as they try to achive excellence in a second language, therefore recreational facilities should be made affordable, also the students should be encouraged to mingle with American students in order to culturally adjust with them   and pur into practice all the theories they have learnt in   class. Also one of the most important things which teachers for this program need to understand is that students enrolled in an ESL program come from very different backgrounds and cultures, therefore the same methodoligies cannot be applied across the board for teachin purposes. Students must be carefully monitered and encouraged to use their strengths to achive succcess in the course.   (Currie, 2003) If one compares the ESL program offered by greemwich Public School with other ESL programs offered, we can say that most ESL programs are similar in conducting theme based activities, which can be selected by asking students what they want to say, moulding the curiculum in children’s interest. Also at this stage most ESL programs are content based, songs are also one of the important keys to success in most ESL progrms. One of the methods which can contribute towards the improvement of an ESL program at Greenwich is that revision of matrial is very important before every new leson taught, this can be best achived with the help of songs before proceeding forward. Each lesson should be broken down into three to four parts, starting with warm up and revision of previous material, then teaching new lesson, for example new vocabulary words etc, the third part should incorporate games or activities t practice the new lesson and the ending of a esson sholud be on a happy thankful note, referably a song. This approach has been teted at ther ESL program and has proved to be very succesful. Different approaches to learning can be adressed thorough ESL games, making learning lessions fun and more effective. Depending on the students theses ESl games can vary from auditorylearnig style in which games involve more listening through peoms or repitation etc. Visual ESL styles ca be used for students who are more comfortable with videos of games involving flash cards etc and finally tactile learnig styles can be used in which â€Å"touch† are used.   (Vernon) In conclusion, if the current ESL program in a School district is evaluated in terms of the comparisons and details mentioned above,   I would say that diverse approach towards the students is missing and teachers are adopting   a homogenous method towards all students. In my opinion more effort needs to be diverted in this angle where different games and teaching styles are used after analysing the capabilities of students and more emphasis should be place on practical learning.

Reviewing and Summarizing the Life of Sarny

A very powerful sequel to the book Nightjohn, Gary Paulsen’s book entitled Sarny: a Life Remembered follows the life of a brave woman who learned to read and write while being held captive by slavery and how she served as an inspiration to her fellowmen. The story is set during the Civil War and slavery was reaching its peak action. Therefore, the book was focused on the important themes related to war such as justice and freedom. Because the narrator was a female slave, the voice of the story is naturally defiant, brave, and full of hope. This is a very qualification of novels that tackle about the lives of Black slaves for it adds character to the wholeness of the plot. In the narration of the book, Sarny was already ninety years old. Her lifetime was devoted her struggles to unite her family, to keep her children safe, and to be able to serve as an educator to other slaves. In Paulsen’s work we witness how Sarny victoriously escaped slavery and how she taught herself to be literate, along with the other slaves she was with. She was married twice and her two children, Tyler and Delie, were separated from her when they were sold as debt payments by their owner. When she was able to leave her owner, she dedicated her time and effort to search for her children. After achieving emancipation, Sarny devoted her time in building a school where she would teach other former slaves to be literate. Other important characters in the story were Lucy, a young slave who has become Sarny’s friend on the road, and Miss Laura, who helped Sarny find her children. These two characters contribute significantly to the direction of Sarny’s life. On the other hand, Sarny also served as an important factor to the developments of these two characters. Sarny is an amazing, informative book to read for all ages, particularly targeting the audience of young adolescents. Even though the main protagonist of the story was already in her nineties, the whole plot of the story would be educational and interesting for all young students who would read this book. There is a fair amount of racial violence and sexual issues that were tackled in the book so the readers should at least be adolescents. But as a whole, Sarny has a very interesting array of characters and its plot is really heartwarming. It is a book that deserves to be highly recommended for it touches important realities of motherhood, family life, slavery, social equality, and freedom.

Salamander Surgery Essay Example | Topics and Well Written Essays - 3500 words

Salamander Surgery - Essay Example Utilitarian philosophy upholds the principle of equal consideration of interests such that all things being equal utmost consideration should be given to that which would bring the most happiness and benefit and would cause less pain and suffering. This assumes that creatures of equal characteristics should be given equal consideration. Australian philosopher Professor Peter Singer in 1975 in a landmark article "All Animals are Equal" (475) argues that discriminating against animals as different from humans is nothing different from racism and sexism. There is a lack of consideration for others who may be different in some aspects but are similar in some. He calls this "speciesism", originally quoting Dr. Richard Ryder, referring to the attitude of bias towards the interest of members of one's own species and against those members other species. Citing Jeremy Bentham, founder of the reforming utilitarian school of moral philosophy, Singer contends that the capacity for suffering and enjoyment forms the basis for equal consideration of humans and animals. ... If racists violates the principle of equality by their prejudice against those of other races, and a sexist violates this same principle by favoring the interests of the members of the same sex, similarly speciesists, without considering that both animals and humans are capable of experiencing pain and suffering, allows the exploitation of other species for their own species' benefit. However, the utilitarian perspective may also be used to justify the use of animals in research to some extent. This opinion considers the benefit of animal research in the scientific field over the cost imposed on animals. Ironically as opposed to anti-speciesist stance of Singer, it is the significant differences between humans and animals such as higher cognition and language ability that forms the basis of this justification. Critics of this variation of utilitarian view maintain that it is unjust to justify animal research with that argument as it supposes that animals are willing participants in research oblivious of the real costs of their involvement (Kimmel, 251). The Rights Argument The main argument against the use of animals in research as articulated by Tom Regan in his article "The Case for Animal Rights" (1985) is that all beings "equally" share an "inherent value" as living creatures. Recognition of this inherent value as individuals can lead to recognition of animals of their right to be treated with respect and not inflicted with any pain or anguish. Regan as a self confessed animal rights advocate calls for the following goals (481): The total abolition of the use of animals in science; The total dissolution of commercial animal agriculture; The total elimination of commercial and sport hunting and trapping; Regan attacks the

Health Service Provision for Older Patients Essay

Health Service Provision for Older Patients - Essay Example The current rise in elderly population due to improvements in health care systems (WHO, 2006) has caused an increase in the number of patients suffering from dementia and hence more research, education, understanding and training with regard to management of dementia patients in hospital setting is warranted. In this essay, the most common cause of dementia in the elderly, Alzheimer's disease, will be discussed through review of literature. The signs and symptoms of the disease, the pathophysiology and various aspects of nursing intervention will be elaborated. Alzheimer's disease Alzheimer's disease (AD) is a common degenerative disease of the brain that leads to dementia (Anderson, 2010). Infact, it is the most common cause of dementia and is incurable. The disease is an acquired condition in which there is impairment of cognition and behavior of the individual that is severe enough to disrupt normal occupational and social functioning of the individual. AD is a major public health problem associated with significant morbidity, impairment and economic consequences (Anderson, 2010). More often than not, the disease is mainly diagnosed after 65 years of age, although, an early-onset variety of AD does exists which presents much early. According to Brookmeyer et al (2007), 1 in 85 people in the world are likely to suffer from AD by 2050. The course of the disease is different for different individuals and thus is the prognosis. The most common early symptom, which is often ignored as an aging feature or stress consequence is the lack of ability to acquire new memories. Other symptoms include changes in cognition and behavior of the individual like irritability, confusion, aggression, mood swings, breakdown in language, withdrawal and long-term loss of memory. As the age advances, various functions of the body are gradually lost, terminating in death. AD imposes severe burden on the caregivers and can influence various aspects of the life of the caregiver detrime ntally. Diagnosis of AD is mainly established through tests for cognition and assessment of behavior. Brain scan is often used as an adjunct to establish the diagnosis. The mean life expectancy of the individual following the diagnosis is about 7 years (Molsa et al, 1995). Pathophysiology The exact cause of AD is still not understood well and there is no treatment which can either cure the disease or prevent the progression of the disease. Even the prevention of the disease is unknown although some researchers are of the opinion that regular exercise, balanced diet and mental stimulation prevent AD (Anderson, 2010). There is some evidence to tell that AD is associated with tangles and plagues in the brain (Ding et al, 2007). Previously, it was hypothesized that decrease in the synthesis of acetylcholine causes the disease. Infact, several treatments for AD were based on that. However, since patients did not respond well to those treatments, the hypothesis could not be maintained. Su bsequently, the amyloid hypothesis was developed, according to which, deposits of amyloid beta were the cause for development of the disease.
